Question

which of the following graphs is not possible class 9​

Answer 1

Answer:

b

Explanation:

The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).

Answer 2

Option b) graph is not possible.

• We are looking at various velocity-time graphs of an object.

• We know that it is not possible for a single object to have two values of velocity at the same time.

So, draw a perpendicular line to time axis on the option b) graph

• You will see that for a single time value, we are getting two values of velocity, which is not possible.

• See the diagram.
